We stayed 9 nights and found this to be an absolutely lovely place to stay. We told ourselves we'd come back here again on our next trip to Bangkok. We had an incredible unblocked view of the city from our room. All staff were pleasant and helpful.
We cooked quite a bit during our stay and found the size of the fridge and freezer in the room to be generous. There's a daily housekeeping service that replenishes bottled water, clears garbage, replaces used towels, and does any other cleaning you may require. The water pressure in the shower and the heating worked great. Airconditioning worked well too as did the cooker hob/hood, wifi etc.
A short walk to On Nut BTS which had 2 small malls flanking it where you can get pretty much anything you'd need while travelling. Overall we found this to be a lovely base from which to enjoy Bangkok!
